IMPROVEMENT IN QUARTZ-CRUSHERS.

Specification forming part of Letters Patent N0. 49,796, dated September 5, 1865.

To all whom 'it' may concern.-

Be it known that I, DANIEL SEX'roN, ofSan Gabriel, in the county ofLos Angeles and State of California, have invented a new and Improved Quartz-Crusher, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable oth ers skilled in the art to make and use the same, reference being had to the accompanying drawings, making` a part of this specification, in which- Figure l represents a side View of my in vention; Fig. 2, a plan or top view of the same; Fig. 3, a detached view of a stamp; Fig. 4, a detached side View of a cam by which the stamps are raised; Fig. 5, an edge View ofthe same.

Similar letters of reference indicate like parts.

rIhis invention relates toanewandimproved machine for crushing quartz; and it consists in the employment or use of a series of cams placed on horizontal shafts, in connection with fixed wheels placed on the rods ofthe stamps, all beingso arranged that the cams willelevate the stamps by acting against the wheels, and

the stamps rotated while being elevated and also while falling, so as to insure the stamps wearing evenly.

A represents a framing, which may be constructed in any proper manner, to supportthe working parts.

B B' B' represent three horizontal shafts, which are placed horizontally in the upper part of the traming,the shafts B having each a cam, C, at each end and a pulley, D, attheir centers, a pulley, D', being also placed centrally on the shaft B, the latter having a driving-pulley, E, at one end.

F is a belt, rope, or chain, which passes around the pulleys D D D and rotates the shafts B B B and cams G in the direction in dicated by the arrows.

G represents stamps, which are at the lower ends of rods H, which work in suitable bearings, a, at each side of the framing and in line with the shafts B B B'. Each rod H has a wheel, I, attached permanently toit, against which the cams C act, the wheels being above the cams. rlhe cams C are eccentrics, as shown clearly in Figs. 1 and 4, and as they rotate they elevate the stamps, and at the same timerota-te them in consequence of the cams turning the wheels and rods as they raise them. The stamps are elevated until the prominent parts of the cams pass underneath the wheels, when they fall until the wheels Icome in contact with the depressed or small portions cf the cams, when they are again raised. The rotary motion of the stamps causes them to wear evenly in consequence ofbeing continually changed in position as they fall, and after coming in contact with the quartz, in consequence ot' the impetus given them as they are raised.

By this arrangement a very simple and efficientquartz-crusheris obtained,one which will work with but little friction, as the camsC are directly under the wheels I and there is no lateral' pressure against the rods H.

Instead of the pulleys D D D and belt F for rotating' the shafts B B'B, gearing may be employed, if desired.

The quartz may be introduced underneath thesta-mpsin the usualorin any proper manner.

I claim as new and desire to secure by Letters Patent- The employment or use of the camsG in connection with the wheels I on the stamprods H, all constructed and arranged to operate in the manner and for the purpose herein set forth.

DANIEL SEXTON.
